Motor starter switch 2-pole Z-MS-1.0/2 248393

Motor starter – protection and control for motors

This two-pole Eaton Z-MS-1.0/2 motor starter is a reliable solution for protecting electric motors in single- and three-phase installations. It provides effective protection against overload, short circuits and other hazardous working conditions, which translates to a longer service life of connected devices and the safety of the entire system. It is a complete device, ready for mounting in an enclosure, which simplifies and speeds up installation.

Functionality and parameters

The Z-MS-1.0/2 starter is designed for applications requiring precise regulation and reliable protection. Its overload release setting range (0.63…1 A) allows it to be adapted to various motor loads. The rated continuous current of 1 A and the short-circuit breaking capacity of 10 kA at 400 V AC guarantee stable operation even in difficult conditions. The magnetic release method ensures a quick response to sudden current changes, minimizing the risk of damage.

• Thermal protection: built-in thermal protection protects the motor from overheating, which is particularly important during prolonged operation under load.
• Screw connection: solid screw connection ensures a secure and durable connection of wires.
• DIN rail mounting: mounting on a standard 35 mm rail (DIN EN 50022) facilitates integration with existing electrical infrastructure.
• Compact dimensions: small dimensions (75 mm height, 36 mm width and 80 mm depth) allow installation in limited space.
• Rated AC-3 operating power: 0.25 kW at 400 V – ideal for applications with motors of this power.

For installers and end users

This starter is not only a protective element, but also a convenient tool for controlling the operation of the motor. The lever mechanism allows easy switching on and off of the circuit. The IP20 degree of protection provides basic protection against touch and dust, which is important both for the safety of the installer during installation and for the end user during operation of the device. This starter is particularly useful in applications requiring frequent starting and stopping of motors, such as pumps, fans or garage doors. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. It protects the circuit against overload and short circuit — like most circuit breakers in this class.
